The Zeiss Sonnar 180mm f/2.8 (C/Y) is a telephoto lens for FF and APS-C format, manufactured from 1978 to 2005 (discontinued). The Carl Zeiss Sonnar T* 180mm f/2.8 is a telephoto lens designed for the Contax/Yashica system. Its maximum aperture of f/2.8 makes it suitable for low-light conditions and for isolating subjects with a blurred background. Thanks to its high-quality optical construction and T* anti-reflective coating, it delivers sharp, contrasty images while minimising reflections and flare effects. It is particularly popular for portraits and sports photography, where its long focal length allows details and expressions to be captured from a distance.
